successive contrast मीनिंग इन हिंदी

The contrast between two full-screen patterns ( full-screen contrast ) always is a " successive contrast ".
When a contrast is established between two optical states that are perceived or measured one after the other, this contrast is called " successive contrast ".
If one object is extreme on some dimension, then neighboring objects are perceived as further away from that extreme . " Simultaneous contrast effect " is the term used when stimuli are presented at the same time, whereas " successive contrast " applies when stimuli are presented one after another.
In 1786 Palmer provided a hypothesis for the complementary nature of the successive contrast effect by stating that it is due to fatiguing of one or two of the light sensor types, an explanation that continues to be accepted as valid, as does his conjecture that the different kinds of sensors take different time intervals to recover upon exposure to strong light.
